The telephone was invented by American inventor Alexander Graham Bell in March 1876. Bell conducted experiments and made advances in the understanding of electricity before he started to work on the idea of the telephone. He then successfully transmitted speech via a device called a "harmonic telegraph." Bell went on to patent the device, launching the world's first commercial telephone system and revolutionizing communication as we know it.
